Rosalyn S. Wainstein, the Sacks’ sister, made the trip from her home in Margate, Fla. She’s 96, but that wasn’t the issue regarding the journey back to Holyoke, she said.

“It’s too cold (here),” said Wainstein, in the 90-degree humidity.

After Mayor Alex B. Morse read a proclamation honoring the Sacks and said that among the city’s amenities now is an $8.1 million senior center soon to open, Wainstein said, “I’m coming back here.”

Ralph Sacks worked for the Parks and Recreation Department and after his brother died, Edward Sacks was a member and chairman of the Parks and Recreation Commission. The brothers gave special attention to Community Field, said David G. Sacks, son of Edward Sacks and a judge in Hampden Probate and Family Court in Springfield.

The city reopened Community Field, off Cherry Street in the Oakdale Neighborhood, June 23 after a year-long, $3.1 million renovation.

The Sacks family was unable to attend that event, so the Parks and Recreation Department arranged the recent ceremony and about 20 Sacks family members attended.

A boulder had long been at Community Field bearing a metal plaque honoring Ralph Sacks. The new plaque added Edward Sacks’ name, and the Sacks’ area at Community Field is the open space behind the Warming House, Recreation Supervisor Peter Leclerc said.

“It’s very nice to have my father and my uncle still remembered after all these years,” David Sacks said.

Morse handed the certificate of congratulations he had read aloud to Wainstein.

“There’s a lot of great things happening in the city. We’re happy to have you back,” he said.

Morse, at 23 the youngest mayor in city history and one of the youngest nationwide, posed for pictures with Wainstein, who is more than four times his age.

Earlier, Wainstein said as she walked across the park that her legs sometimes didn’t work as well as she liked, but her friends in Florida know they can count on her.

“I still drive,” she said, then pointing to Community Field, “Ralph was my brother, he took care of this field.”
